复合粒子的理想化二次量子化
Idealization Second Quantization of Composite Particles
摘要：
提出了一种处理含复合粒子多体系统二次量子化的实用方法。在我们的处理中，与复合粒子相关联的模式被近似地视为与未结合粒子相关联的模式。因此，复合粒子的场算符自然出现在第二量子化哈密顿量中。需要强调的是，第二量子化哈密顿量具有规则的结构，清楚地对应于不同的物理过程。
英文摘要：
A practical method is developed to deal with the second quantization of the many-body system containing the composite particles. In our treatment, the modes associated with composite particles are regarded approximately as independent ones compared with those of unbound particles. The field operators of the composite particles thus arise naturally in the second quantization Hamiltonian. To be emphasized, the second quantization Hamiltonian has the regular structures which correspond clearly to different physical processes.
